transmissibility, we're now seeing clearer evidence, we have about two weeks of data now, that show that it's doubling time is faster than what we saw with the delta variant or the beta variant. so there's now stronger evidence that it's more highly transmissible. it's not definitive, but certainly a strong indication. and certainly from the clinical standpoint, the national database of admissions is now confirming that we're now seeing new data emerging that confirms what we initially saw, that the cases tend on the whole to be milder, with fewer requiring oxygenation. so it's interesting that it's emerging, it's confirming what we know, and certainly no red flags at this stage. >> look, that's the expectation of a virus over time. it becomes more transmissible. and then it becomes less deadly. to that end, have there been any deaths from omicron so far?
